News18.com, the online arm of CNN News18, reported that Delhi’s air quality index (PM2.5) read above 600 on Tuesday, way above Beijing’s 65. In examining the environmental pollution issues facing Delhi, News18.com compared the situation to Beijing and cited an earlier quote by Yale-NUS Assistant Professor of Environmental Studies Angel Hsu in The Guardian, where she commented that the penalties in Beijing are harsh and implementation “isn’t as hard to do as it is elsewhere”.
